FNA- A senior official underlined US President Donald Trump's anger about the nuclear agreement signed between Tehran and the six world powers shows that Iran has received much advantage from the deal.

"Trump described the Joint Comprehensive Plan of Action as worst agreement in the US history and this shows that JCPOA has been beneficial for Iran," Atomic Energy Organization of Iran (AEOI) Spokesman Behrouz Kamalvandi said on Tuesday, addressing a ceremony in the Northeastern city of Mashhad.

"Since Trump's coming to power in the US, the debates over JCPOA have increased in international circles which shows the importance of the nuclear agreement," He said.

In relevant remarks in mid-January, Kamalvandi said his country is monitoring the conditions in Washington to see if the new US administration would opt for compliance with the nuclear deal or confrontation with Tehran.

"At present, the other side (the US) has the two options of interaction or confrontation but undoubtedly, the other side cannot decide about the results and consequences of any measure," Kamalvandi said

"Every one should come to consider this point in his/her calculations that the Islamic Republic of Iran will have reactions appropriate to the behavior and performance of the other side," he added.

Kamalvandi warned that if the path of confrontation is selected by the US, Tehran would show a reaction that would make Washington regret its deed.

His remarks came after Iranian Deputy Foreign Minister for Legal and International Affairs Seyed Abbas Araqchi underlined that the nuclear talks with Washington have ended and the nuclear deal is no more open to renegotiation.

"Except some technical issues, we don�t have any negotiations with the Americans on the Joint Comprehensive Plan of Action and the future of the agreement," Araqchi told reporters in a press conference in Tehran and after talks in Vienna with the negotiators from the six world powers over the latest developments with regard to the nuclear deal.

Noting that the new US president can make any decision he wants about the nuclear deal, he said, "The JCPOA will not be open to negotiations at all."

"Our nuclear talks with the US have ended. We will not enter political negotiations with neither the current nor the future US administration. The JCPOA is a finished case in our view," Araqchi stressed.

He also said that Iran views the extension of Iran Sanctions Act (ISA) by the US as a new sanction and violation of the JCPOA.
